The numbers are the first hard look at how many Americans are struggling to make rent during the coronavirus pandemic. The data come in the first of weekly reports on unpaid rent from NMHC, a landlord trade group.

Only 69% of tenants paid any of their rent between April 1 and 5, compared with 81% in the first week of March and 82% in April 2019, the data show.

The count includes renters who only made partial payments. Many renters who haven’t yet paid may still pay later this month, NMHC said, and an uptick in paperless payments over the weekend may not be reflected in this initial count.

The data come from 13.4 million rental apartments analyzed by several real-estate data firms, including RealPage, Yardi and Entrata.
